It's a dance battle for the ages! Danica McKellar and Candace Cameron Bure were busting moves together onscreen long before either of them ever set foot on the Dancing With the Stars stage. Back in 1990, both actresses appeared in the NBC TV movie extravaganza Camp Cucamonga, which also featured stars including Family Matters' Jaleel White (a.k.a. Steve Urkel), My Two Dads' Chad Allen, The Wonder Years' Josh Saviano, and even future superstar Jennifer Aniston.

The movie is set at a summer camp run by a man named Marvin Schector (Cheers actor John Ratzenberger). Bure and McKellar play rival campers who hate each other at first but become friends when everyone has to rally together to save the camp by making a music video. At one point during the flick, Bure has to learn a routine for the rap they're performing — and when she can't master the moves, McKellar is brought in to teach her. (She ends up just replacing her instead.)

In real life, though, Bure is just fine on her feet. Now 37 and a mom of three, the Full House alum blew Dancing With the Stars judges away with her contemporary dance performance on the season 18 premiere. She and partner Mark Ballas scored 25 out of 30 — one more than McKellar, 39, and Val Chmerkovskiy earned for their foxtrot.

Camp Cucamonga isn't the ladies' only shared history, either. As exclusively revealed by Us Weekly earlier this month, both actresses dated Jeremy Miller back in the '80s. In fact, Miller (of Growing Pains fame) broke up with Bure to date McKellar — which Bure jokingly confronted the Wonder Years actress about on the DWTS premiere.

"I got dumped because he wanted to go out with Danica," Bure (now married to Russian hockey player Valeri Bure) quipped.

Miller, for his part — now married to Joanie Miller — laughed off the love triangle. "I honestly don't remember," he told Access Hollywood. "It was so long ago. I was 12. It was my impression that Candace and I had been distant for a while before I started talking to Danica."
